Since the invention of laser, various applications for lasers in endodontics have been proposed, such as disinfection of the root canal system, canal shaping, pulp diagnosis, and apico-ectomy. One of the major applications of laser in endodontics is apicoectomy. The aim of this article is to review the benefits and drawbacks of laser applications in apicoectomy, including effect on apical seal, effect on dentin permeability, effect on postsurgery pain, effect on crack formation, effect on root-end morphology, effect on treatment outcome, and connective tissue response to laser-treated dentin.

Matrix-assisted laser desorption/ionization (MALDI), surface-assisted laser desorption/ionization (SALDI), and time-of-flight mass spectrometry (TOFMS) imaging are used for visualizing the spatial distribution of analytes. Mass spectrometry (MS) imaging of a sample with a rough surface with a uniform distribution of an analyte does not provide uniform ion intensities in the image. A shift in the value of the analyte ions is also observed.

Photobiomodulation (PBM) therapy stands as an innovative neurostimulation modality that has demonstrated both efficacy and safety in improving brain function. This therapy exerts multifaceted influences on neurons, blood vessels, and their intricate interplay known as neurovascular coupling (NVC). Growing evidence indicates that NVC may present a promising target for PBM intervention.

This review investigated the effects of hypersensitivity treatment on molar-incisor hypomineralization (MIH) using laser therapy, combined or in conjunction with other therapeutic modalities. The review was conducted according to the PICOS strategy (Population, Intervention, Comparison, and Outcome) and was performed in March 2024 using the Web of Science, PubMed, Scopus and Embase. The RoB 2 tool was employed to evaluate the risk of bias.

To assess the efficacy, safety, and stability of refractive outcomes in hyperopic Laser-Assisted in Situ Keratomileusis (LASIK) with and without the application of Mitomycin C (MMC). This randomized, parallel group, controlled multicenter trial included 140 hyperopic eyes. The participants were randomly assigned to two groups: one receiving LASIK with mitomycin C (MMC) (n = 70) and the other receiving LASIK without MMC (n = 70).

Colloidal quantum dots (CQDs) are attractive gain media due to their wavelength-tunability and low optical gain threshold. Consequently, CQD lasers, especially the surface-emitting ones, are promising candidates for display, sensing and communication. However, it remains challenging to achieve a low-threshold surface-emitting CQD laser array with high stability and integration density.
